CD74ACT163M: Synchronous Presettable Binary Counter

The CD74ACT163M is a high-speed synchronous modulo-16 binary counter fabricated with silicon gate CMOS technology. It possesses the speed of bipolar F/FAST™ TTL devices while maintaining the CMOS low power consumption. This integrated circuit is a versatile component designed by Texas Instruments, tailored for high-performance counting applications in a wide range of digital systems.

Key Features

• High-Speed Operation: The CD74ACT163M is characterized for operation from -55°C to 125°C, ensuring reliable performance across a wide temperature range, making it suitable for industrial-grade applications.
• Synchronous Counting and Loading: The counter operation is synchronous, meaning that the outputs change coincident with each other when so instructed by the count-enable inputs and internal gating. This feature allows for precise timing and controlled sequencing.
• Look-Ahead Carry Capability: This feature allows the device to be used in high-speed counting applications by enabling cascading of multiple counters without the need for additional gating.
• Asynchronous Master Reset: The asynchronous master reset (MR) input overrides all other inputs and forces the counter outputs LOW when asserted.
• Outputs Source/Sink 24 mA: The CD74ACT163M has outputs that can source or sink current up to 24 mA, providing good drive capabilities for various interfacing requirements.
• ACT Family CMOS Logic Level: The device is part of the ACT family, offering CMOS logic levels that are compatible with standard TTL logic, which is crucial for mixed-logic environments.

Applications

The CD74ACT163M is suitable for a variety of applications including:

• Industrial controls
• Instrumentation
• Process control systems
• Digital clocks
• Computers and computer peripherals
• High-speed internal and external connection counters

With its robust feature set and Texas Instruments' reputation for quality, the CD74ACT163M provides an efficient and reliable solution for designers looking to implement high-speed counting mechanisms in their digital systems. Its synchronous design, combined with the ability to preset and reset, offers a high degree of flexibility for complex timing and counting tasks.
